Where have I been that I haven't run into this before.  I recently wanted a compact yet secure password management tool that would ideally run from my thumb drive.  Found KeePass, a very slick package.  While I haven't delved deep into the full power of this tool.  It does exactly what I need.  It's quick, runs from my thumb drive and looks to be plenty secure enough and extensible enough to grow with me in the future.  One less thing I need to write for myself!!
